Save the whole web to your research.
Every paper, article, and link you read, captured into your Folio library with the citation already sorted. Verify a page’s references, ask it questions, and never re-type a source again.

Save · Verify · Ask
Three things, from wherever you’re reading.
Capture anything, cited correctly
SaveOne click saves the page you’re on as a proper source — article, paper, book, news, or video. Folio reads the page’s own metadata for the title, authors, and venue, then stamps the accessed date so your MLA and APA citations are right the moment you save.
Right-click any link
SaveYou don’t even have to open it. Right-click a link, choose Save to Folio, and the server fetches the page and enriches the record for you. Build a reading list from a search page in seconds.
Check the citations on any page
VerifyReading a paper or an AI answer full of confident references? Verify pulls out the citations and checks each one against CrossRef, flagging what’s real, what’s uncertain, and what doesn’t exist. Save the verified version in a click.
Ask the page a question
AskAsk anything about what you’re reading and get an answer grounded only in the page in front of you, with nothing invented. It’s comprehension help that never wanders off the source.
Reads the page, not you
The extension only looks at a page when you ask it to save, verify, or ask. It isn’t watching your browsing.
Your library, instantly
Saved sources land in Folio right away, ready to cite, tag, and pull into a draft.
Built on the same integrity core
Verified citations and grounded answers, the same proof-first engine that runs inside Folio.
What it can access
Requests activeTab, storage, contextMenus, alarms, and notifications — enough to read the page you ask it to save and remember your settings. No permission to see every site you visit.
Your sign-in, and how to end it
Your Folio session lives only on your device and refreshes itself automatically every few minutes. Signing out, or removing the extension, clears it immediately — that’s also today’s way to cut off a lost or stolen device, since there’s no remote revoke yet.
Research doesn’t only happen in Folio.
It happens on every page you read. The Folio extension brings the whole web back to your library, with the citation already sorted.
